In the context of neurophysiologic monitoring, what does a higher amplitude waveform indicate?

A higher amplitude waveform in neurophysiologic monitoring is indicative of a stronger nerve response. This means that the neural signals being recorded are more pronounced, suggesting that there is a robust physiological response to the stimuli being applied during monitoring. Such responses can also reflect heightened neuronal excitability or effective conduction of action potentials along the nerve pathways.

Increased amplitude generally correlates with effective neural communication and can be associated with proper neural integrity and responsiveness during surgical procedures. This is significant, as neurophysiologic monitoring aims to assess and maintain the function of neural structures during operations, particularly in cases where those structures could be at risk due to surgical manipulation.
